Hack This?

I have 3 1/2 months before #1 daughter's wedding, and I am day-dreaming about my yard. It's not like I need another project...But this idea has me intrigued, and fits under "spiffy up the house for company" goal. And "cleaning up the sewing room" goal.

Trip with Tiffany to see the wonders of PA (she kept telling me to imagine these planters full of color!):

I see heavy duty felt, grommets to hang on vertical surface, a tarp-like liner against the wall side.

Buy them (watch the video) here. Or make them tutorial here.
These are on my must try list!
